Magical Ammunition

Certain spells connect to better to cartridges as opposed to shells. The price is added on top of the base cartridge or shell, and can be added to the refilling of a cartridge or shell.

Enchanted Ammo

Munitions that are enchanted, don’t necessarily count towards being a magical attack in terms of getting around Damage Immunity or Reduction. Anytime Damage is effected in either value or damage type, then it is considered a magical attack.

Magic Attack: Some ammo is imbued with enough magic to consider the attack magical, while other’s simply seem guided by the magic. A magic attack can be stopped with a counter spell, while non-magic attacks simply lose the enchantment and act as regular munitions for the attack if counter spelled.

Enchanting Ammo

Spell Requirements: You need to expend a spell two times to imbue ammo with the spell, Cantrips can always be imbued.
Save: If the munition you’re enchanting has a spell save, you must use your own Spell Save DC instead of the one listed.
Cost: You also need the proper materials to contain the spell in the bullet or pellets, costing you 20 gp per spell level used, Cantrips are counted as level 1 spells for cost.
Time: It takes 30 minutes to imbue a single bullet, it’s considered non-intensive enough that it can be done during a long rest as long as you aren’t sleeping.

Magic Ammunition only loses it’s magic on usage, there is no time limit on how long the ammo remains imbued.

Spell Attack & Saves

Since you’re wielding both spell and weapon, you use the spell’s casting class attribute (for those with multiple you can use any).

Saves are set at purchase/creation. Depending on the spell casters level. All ammo is assumed to be made by low level individuals unless denoted otherwise. It is usually better to enchant ammo yourself to gain the bonus.

Expending Magical Ammo

Due to the magic stored in the ammunition, any cartridge used will be destroyed on use of magical ammunition, and can not be reused.
